Solr

Solr is the search platform that powers Fusion. There are multiple aspects to Fusion’s use of Solr:

Fusion components manage Solr search and indexing and provide analytics over these collections. Fusion’s analytics components depend on aggregations over information which is stored in a Solr collection.

Fusion collections are all Solr collections.

Application data is stored as one or more Solr collections.

Fusion’s own logs are stored as Solr collections.

A few Fusion service APIs use Solr as a backing store, notably Parameter Sets.
